Polycystic kidney disease

Area of Science:

• Nephrology
• Genetics
• Cell Biology

Background:

• Polycystic kidney diseases (PKD) are major causes of end-stage renal disease.
• Autosomal dominant (ADPKD) and autosomal recessive (ARPKD) polycystic kidney diseases are the primary monogenic forms, linked to cilia dysfunction.
• ADPKD typically affects adults, while ARPKD is a rarer, often severe childhood disease.

Purpose of the Study:

• To provide a comprehensive overview of current knowledge on PKD pathogenesis and treatment.
• To highlight the mechanistic overlap between ADPKD and ARPKD.
• To discuss the implications of genetic diagnosis and emerging therapies.

Main Methods:

• Review of cell biological and clinical research findings.
• Analysis of signaling pathways implicated in PKD pathogenesis.
• Synthesis of information on genetic diagnosis and therapeutic strategies.

Main Results:

• Reduced dosage of PKD proteins disrupts cell homeostasis and key signaling pathways (Ca2+, cAMP, mTOR, WNT, VEGF, Hippo).
• Mechanistic overlap exists between ADPKD and ARPKD pathogenesis.
• Genetic diagnosis and novel therapies show promise for improved patient management.

Conclusions:

• Understanding PKD pathogenesis is crucial for clinical management.
• Further research is needed to address remaining questions about PKD.
• Genetic diagnosis and emerging treatments offer hope for patients with PKD.
